This study investigated the relationship between maladaptive behavior, defined as referral to counseling, and the Adlerian construct of birth order. The birth order variables examined were ordinal position, sex of subject, family density, family size, socio-economic status, intactness of family, age of mother, and sex of sibling. The subjects in this study were 217 school-aged children with academic and/or behavior problems who were referred to an interdisciplinary guidance center. The subjects were assigned to counseling or no-counseling groups on the basis of an interdisciplinary evaluation and staffing, which included an extensive battery of academic and psychological tests.
